DESCRIPTION OF THE PREFERRED EMBODIMENT
Illustrated in FIG. 1 is a point of purchase merchandise display device 10 including four vertically positioned display racks 12. The display racks 12 are provided with inclined trays 14 (FIG. 3) of the type for holding merchandise such as cigarettes. The four display racks 12 are supported to form a square enclosure, and they are each pivotable about a vertical axis from a first position wherein the display racks open outwardly to permit access to merchandise contained in the display racks to a second position illustrated in FIG. 1 wherein the rear walls 16 of the display racks face outwardly. In the second position, the display racks 12 form an inaccessible enclosure housing the merchandise supported by the display racks to thereby prevent pilferage or theft of that merchandise.
More particularly, the display device 10 includes a central vertical supporting pole 18 supporting an upper horizontal support plate 20 which forms a top for the display device 10. The upper support plate 20 is generally square and has four sides 22. The support plate 20 also includes a central aperture 24 for receiving the upper end of the supporting pole 18. The supporting plate 20 also includes an upwardly extending cylindrical collar 26 surrounding the aperture 24 and having a central bore 28. The display device 10 also includes a lower horizontal supporting plate 30 parallel to and spaced below the upper supporting plate 20. The lower plate 30 is also square and has four sides 32 coplanar with sides 22 of the upper support plate 20. The lower planar support plate 30 also includes a downwardly extending central cylindrical flange 36 having a bore 34.
Means are also provided for supporting the upper and lower supporting plates 20 and 30 and the display racks 12 for rotation around the vertical pole 18. An outer tube 40 surrounds the vertical pole 18 and is rotatable around the vertical pole. the outer tube 40 is supported by a collar 42 which is fixed to the pole 18 and which includes an upper surface 44 for supporting the lower end of the tube 40. The upper surface 44 of the collar 42 also supports the downwardly extending central cylindrical flange 36 of the lower plate 30. The upper end of the outer tube 40 is received against the lower surface 47 of the upper supporting plate 20 to provide support for the upper plate 20.
The four vertical display racks 12 are supported between the upper and lower supporting plates 20 and 30, respectively, and adjacent the edges 22 and 32, respectively, of the supporting plates. The four display racks 12 each have opposite end walls 48, a front face 50 and a rear face defined by the rear wall 16. The display racks 12 are supported between the upper and lower supporting plates 20 and 30, respectively, such that, when the display racks 12 open outwardly as shown in FIGS. 2 and 3, each of the sides of the square emclosure formed by the display racks 12 is formed by a front face 50 of one of the display racks and an end wall 48 of an adjacent display rack. When the display racks 12 are pivoted such that the front faces 50 face inwardly, as shown in FIG. 1, each of the sides of the square enclosure is formed by a rear face 16 of one of the display racks and an end wall 48 of an adjacent display rack.
the display racks 12 are each supported for pivotal movement by co-axial upper and lower pivot pins 52 and 54, respectively. The upper pivot pins 52 extend upwardly from an upper wall 56 of the display racks 12 and are engaged within bores 58 in the upper support plate 20. The lower pivot pins 54 extend downwardly from the display rack 12 and are received within bores 60 in the lower plate 30. The pivot pins 52 and 54 are located such that they are equidistant the opposite ends of the sides 22 and 32, respectively, and adjacent those sides.
Means are further provided for connecting the display racks 12 for simultaneous pivotal movement between the first position wherein the display racks 12 face outwardly and the second position wherein the display racks face inwardly and form a closed configuration. In the illustrated construction, the connecting means includes a gear assembly comprised of a large central gear 62 supported adjacent the upper surface 63 of the supporting plate 30 and rotatable around the outer tube 40. The connecting means also includes a plurality of smaller gears 64 each meshing with the larger gear 62. The smaller gears 64 are rigidly attached to the lower surface of the bottom walls 66 of the display racks and include a central bore 68 housing the lower pivot pin 54.
To further explain the support arrangement of the display racks 12, each such rack is pivotally supported adjacent one end wall 48 thereof. That is, the support is adjacent one end wall in the sense that, relative to the length of the rack as viewed in FIG. 1, it is offcenter and closer to one of its two end walls. The opposite end wall, or that spaced further from the pivot moves outwardly of the basic display when each rack moves between its first and second positions.
In operation, manual rotation of one of the display racks 12 causes rotation of one of the smaller gears 64. Accordingly, that smaller gear 64 causes rotation of the larger gear 62 and consequent rotation of each of the other smaller gears 64 such that movement of one of the display racks 12 about the pivot pin 52 and 54 causes simultaneous pivotal movement of each of the other display racks 12.
To provide a means for limiting the pivotal movement of the display racks 12 to an arc of 180°, the larger gear 62 is provided with an arcuate slot 65 (FIG. 2) housing a fixed pin 67 extending upwardly from the lower supporting plate 30. When the pin 67 is positioned against one end of the slot 65, as shown in FIG. 2, the display racks 12 are positioned in their outwardly facing position, and when the pin 67 is positioned against the opposite end of the slot 65, the display racks 12 are positioned in inwardly facing relation.
the display device is also provided with means for locking the display racks 12 in a first position wherein the display racks face inwardly to form a closed configuration protecting the contents of the display device from pilferage or theft an a second position wherein the display racks 12 open outwardly. the lower support plate 30 includes a bore 70, spaced outwardly from the longitudinal axis of the vertical support post 18. As illustrated in FIG. 4, a lock 74 is housed within the bore 70 and includes an upwardly movable cylinder 76 selectively positionable in a bore 72 in the larger gear 62, to thereby prevent relative movement of the larger gears with respect to the bottom plate 30 when the display racks are pivoted to their closed position shown in FIG. 1. Since the display racks 12 are joined by the gears 62 and 64 for simultaneous movement, by locking the gear 62 against rotation with respect to the lower support plate 30, all of the display racks 12 are locked in place.
Various of the features of the invention are set forth in the following claims.
